Definitions

  • the present invention relates to a compact continuous cable pulling device according to the preamble of claim 1.
  • Portable wire rope hoists should be as compact and light as possible, and there should be no limitation on the rope length. These requirements are essentially met by continuous winches, in which the rope is conveyed further by static friction to a drive element and not by winding on a drum.
  • the most common portable cable pulling devices use an alternating clamp pair system that essentially mimics the movements of a person pulling a rope directly with his hands.
  • the simplest pre-tensioning system which can only be used locally, is to apply a certain external force in the non-pulling rope strand, e.g. to produce in the known capstan drives.
  • Another system for ensuring static friction is to press the non-pulling rope strand against the circumference of the traction sheave, for example by pressure rollers. This creates static friction in the pressed area between the rope and traction sheave, which ensures the pre-tension in the non-pulling rope strand when the device is in operation.
  • the condition that guarantees security against slipping is that the static friction generated by the pressure roller pressure is greater than the preload, which is determined according to the Eytelwein law.
  • the pressure exerted on the rope by the pressure rollers can e.g. can be kept constant via spring force or can be automatically adapted to the cable pull.
  • the basic idea of this device sees a traction sheave before, which is slidably mounted on longitudinal guides in a fixed frame.
  • the traction sheave is adjusted together with the drive unit in the longitudinal direction under the action of the cable pull until it is pressed against the counter rollers fixed in the frame.
  • the present invention therefore aims to implement a cable pulling device which provides for the use of pressure rollers which press with a force corresponding to the cable pull against the circumference of the traction sheave without having to resort to a longitudinal adjustment of the traction sheave relative to the fixed frame.
  • this is achieved in that the traction sheave is accommodated in an adjustable manner in the frame and in that a tie rod which is mounted in a longitudinally displaceable manner is provided which carries the pressure rollers at one end and transmits the force exerted on the device in the anchoring point through the other end.
  • the firm mounting of the traction sheave in the frame means a considerable simplification of the construction with a consequent reduction in weight, which makes this construction particularly suitable for portable cable pulling devices.
  • a traction sheave 1 is received in a frame 6 via a ball or roller bearing 7.
  • the rope 2 running tangentially from the traction sheave 1 tends to move the frame 6 in the direction of the cable pull T.
  • the forces acting on the towing device from the outside are indicated in FIG. 1 by arrows in bold. These are the cable pull T and the reaction (-) T effective at the anchor point.
  • the drive is preferably carried out via a drive motor 8 which is fixed to the frame 6.
  • the drive can be of any type, for example electrical, hydraulic or pneumatic.
  • the device can also be operated by a suitable manual drive.
  • a reduction gear between drive 8 and drive pulley 1 will be necessary.
  • this reduction gear can be installed directly in the traction sheave.
  • the example shown in the drawing represents this solution, i.e. a planetary gear built into the traction sheave.
  • the reduction gear consists of a sun gear coupled to the drive 8, a few planet gears 10 and an internally toothed ring gear 12 which is worked out from the drive pulley 1.
  • the planet carrier is identical to the frame 6, and therefore firmly connected to the axes of the planet gears 11, while the internally toothed ring gear 12 rotates.
  • the rope groove 13 can have a wedge-shaped cross section receive.
  • Another integrating component of the cable pulling device according to the invention is a spring which presses the pressure rollers 4 against the circumference of the traction sheave via the tie rod 3.
  • the force exerted by the spring 14 can be very small compared to that exerted by the highest cable tensile force T. It is used to ensure that the rope is carried at the beginning when the cable pull T is still zero.
  • the cable pulling device according to the invention also provides a cable guide 15 which ensures the correct position of the cable in relation to the cable groove 13 when it runs up or down in the starting position.
  • This rope guide must be able to be opened, i.e. be divided into two. This division into two is not shown in the drawing.
